1 Chapter 24 Spinal Trauma Introduction to Spinal Injuries (1 of 2) Annually 15,000 permanent spinal cord injuries Commonly men years old Mechanism of Injury: Vehicle crashes: 48% : 21% trauma: 15% injury: 14% Introduction to Spinal Injuries (2 of 2) 25% of all spinal cord injuries occur from handling of the spine and patient after injury, based upon MOI, that patient s have a spinal injury. Manage ALL spinal injuries with immediate and care Lifelong care for spinal cord injury victim exceeds $1 million. Best form of care is public safety and programs. Spinal Anatomy and Physiology: Vertebral Column (1 of 2) bones comprise the spine. Function Skeletal support structure Major portion of axial skeleton container for spinal cord Vertebral body Major -bearing component Anterior to other vertebrae components Spinal Anatomy and Physiology: Vertebral Column (2 of 2) Cervical Spine (1 of 2) vertebrae Sole support for head Head weighs pounds C-1 (atlas) Supports Securely affixed to the occiput Permits Cervical Spine (2 of 2) C-2 (axis) Odontoid process (dens) Projects Provides point so head can rotate C-7 spinous process (vertebra prominens) 1
2 Thoracic Spine (2 of 2) vertebrae 1st rib articulates with Attaches to transverse process and vertebral body Next nine ribs attach to the and superior portion of adjacent vertebral bodies rib movement and provides increased rigidity Thoracic Spine (2 of 2) Larger and than cervical spine Larger muscles help to ensure that the body stays erect Supports of the thoracic cage during respirations Lumbar Spine vertebrae Bear forces of and lifting above the pelvis and thickest vertebral bodies and intervertebral disks Sacral Spine fused vertebrae Form posterior plate of Help protect urinary and reproductive organs Attach pelvis and lower extremities to skeleton Coccygeal Spine fused vertebrae Residual elements of a Spinal Cord Transmits input from body to brain through 31 pairs of nerves Conducts motor impulses from brain to muscles and organs Protected by 3 layers of meninges Mater Mater Mechanisms of Spinal Injury (1 of 3) Extremes of Motion: Hyperflexion: Kiss the Chest Excessive bending Mechanisms of Spinal Injury (2 of 3) Axial Stress: Loading: compression of spine Falls, lifting too much weight 2
3 Compression common between T-12 and L-2 : Opposite of axial loading: stretching of the spine Hangings, injuries Combination Distraction/Rotation or Compression/Flexion Mechanisms of Spinal Injury (3 of 3) Other MOI: Direct trauma Mechanisms Causing Spinal Injury Column Injury (1 of 2) Movement of vertebrae from normal position (incomplete dislocation) or Dislocation Fractures Spinous process and process Vertebral Ruptured intervertebral Column Injury (2 of 2) Common sites of injury: C-1/C-2: vertebrae C-7: Transition from flexible cervical spine to T-12/L-1: Different between thoracic and lumbar regions Cord Injury (1 of 4) Concussion: Similar to cerebral concussion and transient disruption of cord function Contusion: of the cord Tissue damage, vascular leakage and Cord Injury (2 of 4) Compression Injury: Secondary to: -displacement of the vertebrae - of interverterbral disk -displacement of vertebral bone - from adjacent tissue Cord Injury (3 of 4) Laceration: Causes Bony driven into the vertebral foramen 3
4 Cord may be to the point of tearing Hemorrhage into cord tissue, swelling and disruption of Hemorrhage is also associated with contusion, laceration, or stretching Cord Injury (4 of 4) Transection Cord Injury: Injury that partially or completely the spinal cord S/S depends on of transection Complete Transection Cervical Spine: Incontinence Respiratory Below T-1 Incontinence Points of Paralysis Incomplete Transection Cord Injury (1 of 2) Cord Syndrome Anterior vascular disruption Loss of motor function and sensation of pain, light touch, & temperature below injury site Retain motor, positional and vibration sensation injury Cord Syndrome Hyperextension of cervical spine Motor weakness affecting upper extremities dysfunction Incomplete Transection Cord Injury (2 of 2) Brown-Sequard s Syndrome Penetrating injury that affects side of the cord (injured side) sensory and motor loss (opposite side) pain and temperature sensation loss General S/S of Spinal Injury Extremity Pain with & without movement Tenderness along spine Impaired breathing Spinal (rare) Loss of bowel or bladder control Nerve impairment to extremities 4
5 Spinal Shock (1 of 2) Spinal shock is a temporary form of shock that presents with hypotension,, and the signs and symptoms of cord injury. Spinal Shock (2 of 2) insult to the cord Affects body below the level of injury Affected area may be: Without feeling Loss of movement ( paralysis) Frequent loss of bowel & bladder control Priapism Hypotension secondary to Neurogenic Shock (1 of 2) Spinal-Vascular Shock Occurs when injury to the spinal cord disrupts the brain s ability to control the body Loss of tone Dilation of arteries and veins which; - vascular space -Results in relative hypotension -Reduced cardiac -Reduction of the strength of contraction Neurogenic Shock (2 of 2) Autonomic Nervous System (ANS) loses sympathetic control over adrenal medulla Unable to control release of & norepinephrine Thus warm dry Could depress S/S of Neurogenic Shock Cool, Moist & Pale skin above the injury Warm, Dry & Flushed skin the injury Priapism in males Other Causes of Neurologic Dysfunction Any injury that affects the nerve impulse s path of travel Dislocations syndrome Assessment of the Spinal Injury Patient Scene Size-Up Put special emphasis on your analysis of the mechanism of injury with a potential spinal injury patient. 5
6 Determine of spinal trauma Maintain suspicion with injuries If unclear about MOI take spinal precautions Primary Assessment (1 of 2) ABC s Immobilize spine as needed Consider Oral or Intubation if required Maintain in-line c-spine control Primary Assessment (2 of 2) Control C-spine injury Intoxicated patients All to the torso Maintain manual stabilization Vest style versus rapid extrication Maintain alignment Increase of pain or resistance, restrict movement in position found Rapid Trauma Assessment (Scan) Perform a RTA on all patients with: Suspected or likely spinal cord/column injury Multi-system trauma patient Evaluate for: Neck Deformity, Pain, Crepitus,, Tenderness Bilateral Extremities: Push, Pull, Grips Motor & Sensory Function Sign Test Babinski s Sign Test Stroke aspect of the bottom of the foot Evaluate for movement of the toes of the toes and lifting of the great toe is a positive sign Indicates injury along the pyramidal (descending spinal) tract Positive Babinski s sign is normal in patients under years of age May be permanent or Vital Signs and Reassessment Vital Signs: Body Pulse, BP, Respirations Reassessment: Recheck elements of initial assessment Recheck vital signs Recheck Recheck any deviations Spinal Clearance 6
7 Some services have protocols to the spine, thus requiring no spinal immobilization Controversial but growing in popularity Follow local Never clear spine without protocols Immobilize based on Sample Spinal Clearance Protocol Management of Spinal Injuries Spinal Alignment Move patient to a, in-line position Position of function Hips and knees should be slightly for maximum comfort and minimum stress on muscles, joints, & spine if possible Place a rolled blanket under the knees ALWAYS support the and neck Contraindications to Neutral Position Movement causes a noticeable increase in Noticeable met during procedure Increase in neurological deficits occurs during movement Gross of spine LESS MOVEMENT IS BEST! Manual Cervical Immobilization of Seated Patient Approach from Assign a care giver to hold GENTLE manual Reduce loading Evaluate posterior cervical spine Position patient s head slowly to a neutral, in-line position Manual Cervical Immobilization of Supine Patient Assign a care giver to hold manual traction Adult Pad head off ground 1-2 if needed to assure neutral, in-line position Child Position head at ground level: Avoid flexion. under upper shoulders Pad as Needed C-Collar Application Apply the as soon as possible Assess neck prior to placing C-Collar limits some movement and reduces axial loading DOES completely prevent movement of the neck Size and apply according to the manufacturer s recommendation Do NOT release manual control until the patient is fully secured in a spinal device 7
8 Standing Takedown (1 of 2) Minimum rescuers Have patient remain immobile Rescuer provides manual stabilization from neck Size and place c-collar Standing Takedown (2 of 2) Position board patient Grasp board under patient s Lower board to ground Secure patient WITH PARTNERS AND PATIENT!! Helmet Removal Remove Helmet if: (1 of 2) Helmet does not immobilize the patient s head within Fits too Cannot securely immobilize the helmet to the long spine board Helmet prevents care remove mask only if football helmet Remove Helmet if: (2 of 2) Helmet prevents assessment of anticipated injuries, burns, etc Present or anticipated airway or problems Removal will not cause further If helmet is removed, remove pads as well to maintain alignment Helmet Removal Technique 2 Rescuers Remove face mask and strap Immobilize head Slide one hand under back of and head Other hand supports anterior neck and jaw 2 nd rescuer removes helmet TRANSPORT and any other safety device (HANS) with patient is the KEY Helmet removal may be a tricky endeavor.you should familiarize yourself with the types of used by sporting teams and venues in your area. Movement of the Spinal Injury Patient Any movement MUST be Move patient as a unit NO PUSHING Move patient up and down to prevent lateral bending 8
9 Rescuer at the head CALLS all moves ALL MOVES MUST be slowly executed and well coordinated Consider the positioning of the patient prior to beginning move Types of Moves Log Roll Slide Rope-Sling Slide Orthopedic Stretcher Vest-Type Immobilization Rapid Long Spine Board Diving/Swimming Injury Immobilization In the During all movement of a spinal injury patient, keep the spine in the neutral, inline position by keeping the patient s eyes facing directly, and the shoulders, pelvis, and toes in the same. Transport Considerations Make sure patient is fully immobilized transporting route is not always the best Often, the smoothest route is more important than the quickest route Try to avoid that can cause unnecessary jarring and movement of the patient Give the patient a gentle trip Consider air transport if in terrain Medications and Neurogenic Shock (1 of 2) Fluid Challenge to fill vascular space -Isotonic Solution ( or NS) -At least ml initially for an adult -Monitor response and repeat as needed to maintain systolic BP PASG - -Research shows no positive outcome Medications and Neurogenic Shock (2 of 2) to increase BP Atropine to speed up heart if neurodeficit is identified Reduce the body s response to injury Reduce swelling and pressure on cord Administered within 1st 8 hours of injury Summary is the single most important indicator for need to immobilize 9
10 Ability to walk and move is not sufficient to rule out spinal injury movement of the patient is of utmost importance Use IV fluids to top off the tank and fill space 10
